REFRIGERANT HANDLING AND SAFETY
Do not proceed with any aspect of a procedure if you do not fully understand the procedure and know what result to expect. Understand that pressure exists in refrigeration systems. Be careful.
REFRIGERANT
SEAFROST is charged with REFRIGERANT-404a. REFRIGERANT-404a is a blend of HFC refrigerants. It is odorless. Its boiling point is -57. Degrees F. at sea level. It is heavier than air. It's label and container color is orange.
GENERAL SAFETY THIS IS IMPORTANT. READ THIS!
R-404a is safe if handled properly. Avoid breathing vapors and prolonged skin exposure. Avoid using in areas of open flames. The vapor is heavier than air and may reduce oxygen available for breathing. Use with sufficient ventilation to keep exposure below recommended limits. Do not mix with air for leak testing or use with air for any purpose above atmospheric pressure. Liquid R-404a will freeze skin. It's especially dangerous to the irreparable tissues of the eyes.
--WEAR EYE PROTECTION--
Do not pressurize an empty system with R-404a without first evacuating the system with a vacuum pump.
WARNING: DANGER NEVER OPERATE A SYSTEM WITH THE HIGH SIDE (DISCHARGE) OPEN TO THE REFRIGERANT SUPPLY. PRESSURIZATION OF THE REFRIGERANT SUPPLY COULD CAUSE IT TO BURST.
